Specification of Letters Patent.

Application filed October 3,1905. Serial No, 281,184.

To all whom it may concern.-

Be it known that I, JAooB K. ALTEMUS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Yarn-Winding Machines, of which the following is a specification.

My invention consists of certain improvements in the weft-winding machine shown in Letters Patent No. 373,675, granted on the 22d day of November, 1887, to Robert Megowan, the object of my improvements being to lengthen the term of usefulness of various elements of the driving and supporting devices used in connection with the windingspindle of said machine. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which .Figure 1 is a transverse section of sufiicient of a weft-winding machine of the character to which my invention relates to illustrate my present improvements thereon, and Figs. 2 and 3 are perspective views further illustrating said improvements.

Referring, in the first instance, to "Fig. 1 of the drawings, 1, 2, and 3 represent three longitudinal beams which carry the various spindle bearings or supports of the machine, 4 representing the driving-drum, and 5 the Winding-spindle, which has a drum 6 resting upon the driving-drum 4 and rotated by contact therewith, said driving-drum being centrally recessed for the [reception of the driving-belt 7.

The yarn is wound directly on the outer end of the spindle 5 in the form of a cop, the nose portion of said cop resting in a tapering former-head 20, mounted upon the front beam 1 of the machine, the rear end of the spindle having its bearing in a box 21, which engages a slotted bracket 22 on the rear bar 3 and the intermediate portion of the spindle passing through a slotted. bracket 23 on the intermediate bar 2.

The base of the slot in vides a beveled seat for beveled under side of and the latter is free to move in the slotted bracket 22 both vertically and in a direction parallel with the spindle 5. Hence when the winding operation is approaching its close and the spindle 5 is moved rearwardly in its bearings, so that the end of the drum 6 or other projection upon the spindle strikes the inner end of the box 21, the latter is by con tinued rearward movement of the spindle the bracket 22 prothe correspondinglythe bearing-box 21,

also caused to move rearwardly and is at the same time caused to rise, because of its beveled bearing on the bracket, until finally the drum 6 is lifted clear ofthe driving-drum 4, and the rotation of the spindle is therefore arrested.

Substantially the same mode of operation attended the construction of the patented device before alluded to; but in that case the bearing 21 was simply a block with a recess in the top for the reception of the spindle 5, whereas in the present case I use a box having therein a longitudinal opening 24, whose vertical dimensions are somewhat greater than the diameter of the spindle 5, this box having a beveled or inclined bottom surface and also a correspondingly beveled or inclined top surface, so that when the bottom of the opening 24, which normally serves as a support for the spindle 5, becomes unduly worn the block can be reversed in the bracket 22 and the unworn top surface of the opening thus rendered available for the support of the spindle, the life of the bearing being thereby doubled.

,The bearing-block has the usual front and rear flanges 25 and 26 for limiting its longitudinal movement in respect to the bracket 22.

The spindle-drum 6 rests upon the drivingdrum 4 slightly to one side of a vertical line drawn through the axis of said driving-drum. Hence there is a slight lateral thrust upon the spindle 5, tending to cause it to bear against one side of the slot in the intermediate bracket 23, and I provide that side of the bracket with a wearing-shoe 27, consisting of a slotted yoke which can be slipped onto said side member of the bracket and retained in position vertically either by its own weight or by means of a cotter-pin or other available fastening. When the lower portion of this shoe becomes worn by reason of the lateral pressure of the spindle 5 thereupon, the shoe can be removed, reversed, and reapplied, so as to bring a fresh bearing-surface into play, the bracket 23 being entirely relieved from wear, since the spindle 5 does not rest on the bottom of the slot in said bracket, but is supported by reason of its rear bearing in the box 21 and by the bearing of the nose of the cop in the forming-cup 20.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination in a winding-machine, of the winding spindle, a bearingblock therefor having beveled top and bottom faces, and a spindle-receiving opening Whose vertical dimensions are in excess of the diameter of the spindle and a support for said bearing-block presenting a beveled seat thereto, substantially as specified.

2. The combination in a Winding-machine, of the Winding-spindle, a drivingdrum, a supporting-bearing for said spindle, and an intermediate steady bearing having a detachable shoe providing a side contact- Eearing for the spindle, substantially as speci- 3. The combination in a .winding-machine, of the Winding-spindle, a drivingdrum, a supporting-bearing for said spindle, and an intermediate steady bearing having a detachable and reversible shoe providing a side contact-bearing for the spindle, substantially as specified.

4. The combination in a Winding-machine, of the Winding spindle, a drivingdrum, a supporting-bearing for said spindle, and an intermediate steady bearing having a detachable shoe consisting of a slotted yoke applicable to a vertically-projecting member pit said steady bearing, substantially as speci- In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
